OVERDRIVE® PROCESSOR SOCKET SPECIFICATION
17.6.3.2.
PENTIUM
®
PRO PROCESSOR COOLING REQUIREMENTS
(SYSTEMS TESTING ONLY)
The Pentium Pro processor case temperature must meet the specifications of the Pentium
Pro processor. Thermal testing should be performed under worst case thermal loading (Refer to
Section 17.6.3.1., “OverDrive® Processor Cooling Requirements (Systems Testing Only)”
for loading description), and with a cooling solution representative of the OEM’s cooling
solution. Refer to Table 11-5 for the Pentium Pro processor case temperature specification.
17.6.3.3.
VOLTAGE REGULATOR MODULES (SYSTEMS EMPLOYING A
HEADER 8 ONLY)
The case temperature of the voltage regulator on the OverDrive VRM must not exceed the spec-
ification of Table 17-7.
